Multi-Energy Systems and Grids

NTU_PageContent

To develop cost-competitive solutions to improve its energy efficiency, reduce carbon emissions, and broaden its energy options, Singapore has embarked on an energy transition which includes increased focus on natural gas and LNG and on deployment of at least 350 MW of solar energy by 2020.

Introduction of renewables and distributed generation will need a revamp of Singapore’s grid system into an interoperable network, leveraging two-ways flows of energy and communication. The next generation grid that will leverage on solid state transformers will be a digital grid that will also allow Singapore to maintain grid resilience to counter new load and source dynamics in the distribution networks.

Another key factor to be considered is although smart grids have been studied extensively in the recent years, grids which are emerging in many industries and districts are Multi-Energy Grids which need optimization of not just electricity, but also thermal energy (both heat and cold) as well as gas / chemical energy. Thus this IRP focuses on the next generation grids both: next generation electric grids and also next generation multi-energy grids and multi-energy systems.
